I would nominally agree with this logic, but surely the exact same applies when voting? Should people not bother voting because they are just one in a sea of many?
In the United States I would say it depends where you live. I'm a Democrat in a forever-red state. My vote for President will never matter as long as the Electoral College is there.
I still vote for state-wide and local matters and that is where my vote really does count.
